The EVQ5862-LT-00A evaluation board is designed to demonstrate the capabilities of the MPQ5862-AEC1, a dual-channel, high-side (HS) power switch for a nominal 1.5A load per channel. The device covers a 5V to 16V input voltage (V_INx, where x = A or B) range. The MPQ5862-AEC1 supports both a default internal current limit (2.4A) and a configurable, high-accuracy current limit via the I²C. This helps clamp the inrush current under short-circuit conditions, which improves system reliability. A selectable start-up slew rate also helps reduce the inrush current during start-up. In addition, fast-off functionality can quickly shut down the device if the channel current increases sharply.

The MPQ5862-AEC1 communicates with the microcontroller unit (MCU) via the I²C interface. The device supports up to 6 addresses, set via an external resistor. With the help of an internal analog-to-digital converter (ADC), the channel currents, supply voltages, reference voltage (V_REF), and output voltages can be obtained without additional external circuitry. The device integrates full diagnostics and protections, including input over-voltage protection (OVP) and under-voltage protection (UVP), output OVP for each channel, open-load and short-to-battery detection, over-current protection (OCP), short-circuit protection (fast-off), and over-temperature (OT) shutdown.

Average and peak current detection improves diagnostic reliability in driver monitoring systems (DMS). The fault status can be reported via both the FT pin and the I²C.

The MPQ5862-AEC1 is available in a TQFN-17 (3mmx4mm) package. It is available in AEC-Q100 Grade 1 and is compliant with AEC-Q100-012 Test Grade A.
